Demon's Souls [BLES00932]

Hello.
After some RPCS3 new builds updates, framerate got drastically improved for me, but sadly, stability gone down - game crashes after 1-2 minutes of playing every time, no matter what I do or where I am in game.

Stable 30 fps most of the time, in some spots and situations (like breaking destructable objects like boxes, crates, barrels etc.) fps drops to minimum 20 fps and stutters a lot, but it's tolerable.

US version (BLUS30443) works even worse - worse framerate, crashes after few seconds when I enter game world. And strange Bandai Namco logo appears after booting the game (overlays every other company logos like Atlus, Sony, Havoc etc.)

I'm sending RPCS3.log file in attachment.

RPCS3 v0.0.3-5-0a4776d Alpha
BLES00932
PS3 firmware 4.81 (latest official)

Settings where I get best performance (hmmm maybe makes no sense posting it, tested tons of settings combinations, all time crashes after moment of playing, only setting both decoders to "precise interpreters" prevent crashes, but it brings totally unplalayable framerate):

PPU - LLVM
SPU - ASMJIT
Auto Load Libraries
Preffered SPU Threads - 2
Lower SPU Thread Priority + Enable SPU loop detection
Vulkan - Write Color Buffers + Invalidate Cache Every Frame
XAudio2 + Downmix to stereo

PC Specs:
Windows 7 Ultimate x64 SP1
Intel Core i5 7500 3,4 Ghz Quad-Core
MSI GTX 1060 Gaming X Plus 6GB GDDR5
16 GB DDR4 RAM
Gigabyte GA-B250M-D3H
Nothing overclocked, not tuned up in msi/gigabyte/intel/bios settings

Thank You.
